Final answer:
The felsic minerals from the options listed are A. feldspar and C. quartz, which are light-colored, silica-rich, and commonly found in felsic rocks like granite and rhyolite.Option D is the correct answer.
Step-by-step explanation:
The minerals that are considered felsic are typically lighter in color and rich in silica (SiO2). Based on the options provided, the felsic minerals are A. feldspar and C. quartz.
Feldspar includes minerals like orthoclase and plagioclase, which can be found in coarse-grained intrusions of igneous rocks and have high silica content. Quartz, known for its clear, glassy appearance with no cleavage, is also a major component of felsic rocks like granite and rhyolite.
While biotite (B) and amphibole (D, specifically hornblende) can be present in felsic rocks, they are not considered felsic minerals. Biotite is a dark mica, and amphibole is a dark, long crystal mineral; both are commonly found in more mafic rocks.
